Clinometer+ Slope

Now a miter angle calculator for crown molding - measure any corner and get exact miter and bevel angles for perfect compound cuts.

Clinometer+ Slope turns your iPhone into a precise angle and slope meter with four purpose-built modes — and now keeps a full history of every reading.

FOUR MODES • Auto — radial gauge with degrees + grade % + ratio. • Roof Pitch — rise:run (6:12 etc.) + degrees + standard pitch matching (1:12 ~ 12:12). • Slope — grade % + walking categories (level / gentle / moderate / steep / severe) + ADA ramp / ladder safe references. • Tilt — bubble level visualization + ±degrees, perfect-level indicator.

WHAT'S NEW • Measurement History — every reading is auto-saved with a 7-day trend chart and insights like "+12% vs your 7-day average". • Notes & Favorites — add a note ("kitchen floor", "patio") and star to any saved reading. • Compare Mode — pick two saved measurements and view the difference side by side. • Reference Library — ADA ramp max (1:12), standard roof pitches (3:12 / 6:12 / 8:12), ladder safe angle (75°), ramp categories, climbing slopes. • Share Result — share your current angle as an image. • CSV Export — share all your measurements as CSV for spreadsheets.

CORE FEATURES • Real-time angle measurement (degrees / grade % / ratio) • Kalman-smoothed sensor readings • Hold function (freeze current reading) • Calibrate Zero (set any surface as the 0° reference) • Min / Max tracking with elapsed time • Live trend chart
